Hen Dead in Nesting Box This Morning.

[Bock-Bock-Bagock]

This morning I found my black hen, CoCo, dead, on her side in the nesting box. I was reading previous threads and people suggested if their comb was a dark purple, it might be a heart attack. In my girl's case, her comb and wattle were very pale. She has a pretty red set usually.
***Edit***
She is still less than a year old and only started laying maybe two months ago.
She wasn't showing any signs of issues the last few days. I am pretty sure she was laying ok. I'm not exactly sure who's eggs are who's for some of them. But I was going by count. I had 5 hens and I'd get about 5 eggs a day. Some days 4. Her egg looks pretty similar to the Buff Orpington's eggs. Kind of a pale off-white color. And they were about the same size too.
I did notice a mite problem currently, which I am treating. None of the chickens seem to have mites on them, just in the coop. She did have mites on her dead body.

Sorry for your loss. Do you want to try doing a necropsy yourself?

I'd rather not cut open my girl. I know she's gone and couldn't feel it. But I have my ladies for eggs, not meat. So it's pretty offputting to do something like that.

The necropsy would be to try to find out why she died.

Sorry about losing your hen. Mites cause anemia. If you saw mites, I would treat all of your birds with permethrin garden dust or 0.5% spray. Remove all bedding from coop, and nests, and then use permethrin to spray the roosts, nest boxes and coop before adding new bedding. If you still have the body you could keep it cold and have the state vet do a necropsy on her to look for a cause of death. Here is a list of state vets:

I know the local co-op has a spray that is supposed to be for chickens. Last year I used DE in the coop and didn't have too many problems. They just recently sprang up now that it's staying warm.
